HOT-WATER RADIATOR.

SPECIFICATION forming part of Letters Patent No. 407,785, dated July 30, 1889.

' Application filed December 22, 1888. $erial No. 294,442. (No model.)

To aZZ whom it may concern:

Be it known that I, EUGENE SOLOMON MANNY, a citizen of the Dominion of Canada, residing in the city and district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Hot- Water Radiators; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to a hot-water radiator composed of several sections joined together by means of a longitudinal bolt and communicating with each other at their inferior part only.

The main feature of my invention is a device for carrying off the air which collects at the top of each section, and which shall be fully explained hereinafter.

, Referring to the drawings, similar letters refer to similar parts throughout the several views.

Figure 1 is an elevation of a section showing portions in cut. Fig. 2 is a side elevation; Fig. 3, an end elevation, shown partly in section; and Fig. 4, adetail section of air-tube.

A is a section composed of two hollow columns B and O and a central portion D, and joined together at their upper portion E and lower portion F, the latter having a circular projection Gon each side. These projections are faced, so that when they are joined together by means of a bolt which passes through the hole H and drawn tightly to,

get-her they make a perfectly tight joint. These projections G are provided with the openings I and J, the opening I being for the inlet of the hot water, which ascends the columns B and passage D. Then it reaches the top E, it descends the columnn O and passes out toward the furnace through J, the openings I and Jbeing separated by means of the partition K, which passes around the holes H and L and terminates at the foot of the column O. (The whole shown in dotted lines in Fig. 1.) Most necessarily the hot water ascending through the two passages B and D has a much less velocity than the cooled water descending through the column O, for the simple reason that the combined areas of B and D are greater than that of column 0. The openings L, all coming opposite one another, form a continuous tube, the use of which shall be explained hereinafter.

As can be seen, the hot water entering the passage I at one end of the radiator each section is equally heated, for the simple reason that they are all supplied with water having the same temperature. At the upper end E is placed two lugs M, having holes N, through which pass bolts to keep the upper portion of the section firmly in place. The whole is covered by means of the piece 0. Now, the portion of my invention I want to call special attention to is my device for carrying off the air which always collects in the upper por-' tion E of the several sections. It is very simple, and consists of the tube P, placed in each section, joined at one end to the top Q of the radiator, which is slightly re-enforced at R to receive the end S of the tube P, which is here plugged with a piece of lead T. At its other extremity the tube P is forced into the hole V in the lower part of the radiator, so as to make a tight joint, and thus communicates with the passage L, theprojection IV having for its object to insure a good bearing for the end of the tube P. At the upper end of the tube P are placed two small openings Y Y, and inside the tube itself a partition Z, pierced with a very small hole I), so that the least water possible will pass out with the air through the tube P. Now, at the extremity of the passage L, formed by several sections joined together, are placed valves, so that to let out the air all that is necessary to do is to open one of these valves, for two can be used one at each end-01 only one, as found suitable.

The holes Y Y are so high up in tubeP that the hot water seldom reaches them, and the hole I) in the partition is so small that the water will not rush through it unless the airvalve is opened to relieve the pressure, and even then, from the extreme smallness of the hole, there will be no objectionable outrush of water. If a very small tube Were used, it would soon become choked up; but the partition Z being so thin the hole 5 will usually remain open and can easily be got at and cleared by removing the plug T.

WVhat I claim is air-hole and secured in the said tube a little IO In a hot-water radiator, the combination, below the holes Y, substantially as set forth. with a section of the main body provided with In testimony whereof I aflix my signature in water-passages and with the air-passage L in presence of two witnesses. 5 the lower part of it, of the tube P, communieating with said passage L and having holes EUGENE SOLOMON Y at its upper end and communicating with WVitnesses:

the upper part of the water-space, and the C. LEDUO,

thin partition Z, provided with a very small J. EMILE VANIER.
